Hi Welcome to Dell Tech Support.
We’ve all heard of BIOS, but what exactly is it and what does it do?
BIOS stands for Basic Input and Output System.
BIOS contains all the basic software required to…Boot the motherboard Check the installed devices and Load the operating system.
The main functions that are allowed to be customized within BIOS are the Date and Time, the Boot Sequence, Advanced Boot settings, System passwords for the administrator and the hard drive, and Adjusting the number of cores used by the processor and the operating speed.
Every time you turn on your computer, it goes through four processes: CHECK the information stored in CMOS, a tiny memory located on a chip on the motherboard, and check the information about the hardware configuration. POST makes a brief test on the physical components, such as the hard drive and the processor, to see if everything is okay. ACTIVATE the components installed on the computer, such as expansion cards, like the video card and the external audio. Finally the BOOT; starting the Operating System.
Basically, BIOS is the system behind your system. It has a lot of responsibility. It is what’s happening behind the scenes every time you turn on your computer.
